PN EUMATiC. COTTON-HANDLING APPARATUS= LPECIITICATION forming part ofLette atent Na /78,983, dated January 3, 1905.

Application filed June Eserial No. 211,057.

To 77 11-72mmv it WN /MIIPFfRQ citizen of the United. States. residingat- Mart,

in the county of McLennan and State of Texas, have invented a new anduseful Pneumatic Cotton-Handling Apparatus, of which the following is aspecification.

. This. invention relates to pneumatic cottonhandling apparatus; and ithas for its object to provide a device of this class by means of which aconsiderable saving may be effected in the labor of handling cotton.

To this end my invention comprises apparatus for unloading cottonsimultaneously,

from two wagons and for conveying the cotton from one wagon to a storageplace and from the other wagon to feeding devices for p Screens 11 and12 are disposed in the suction supplying a battery of gins.

My invent-ion further comprises means for blowing the lint from the sawsto the con- 5 denser-s. and for blowing the seed to the seedhouse,t o acar, or to some other place of deposit. The invention further comprisesmeansfor conveying into the seed-ductanydirt or trash tially in themannerwhich will be hereinafter in theclaims.

Int-he accompanying drawings, Figure 1 is a diagrammaticviewillustrative of my inven- Fig. 2 is a sectional view of thecompressing-chamber, showing the inlet of the fully, described, andparticularlyTointed out seed-ducts. Fig. 3 is a sectional detail viewtakenllirough one of the gin-stands. Fig. &

InFig; 1 of the accompanying drawings 1 have "diagrarmn'aticall-yillustrated a battery of four gin tands, each of said gins being designat'ed-l.

I receives the blast discharged from ,affan 3, Be it known that 1,ROBERT B. Ltz n'aega mounted in a casing 1', the d1schargc-opening fwmeh is suitably connected with the lower part .of"said"compiessiag mtion-tube 5, connected with tvehiftaiieb i i fi";

pipes 6 and 7 between the traps 9 and 10 and the main'suctioi'rpipe 5.These screens serve,

" primarily, as deflectors bymeans ofwhich the cotton is deflected intothe traps; secondarily, they serve as sieves through which dirt and"loose. trash maybe separated from the cotton and permitted to passthrough the branches and 7 into the main suction-tube 5 andfrom 75thence through the fan-case into the compressing-chamber 2, within whicha deflector 13 is disposed to guide such trash into the seed-duct 11,into which the seeds are conveyed from the gins through suitableconductors or by suitable means. (Not shown.) l he ends of thecompressing-chamber are connected with air-ducts 15, one at each end,andeach directed between a pair of gin-stands. Above each pairof ginstandsis disposed an. air-chamber 16, having an o ienin 1T; whichis connectedwith the enlarged discharge end of one of the air-ducts 1.5.

Within eachair-chamber 16 is furthermore placed a pair of inclinedboards 18, comblning with the top of sa id air-chamberto formatriangular deflector which dividesthe discharge from thecnlargcd'opening l7 oft-he duct 15,550 as to divert suchdischargeequallyintoboth ends of'the air-chan berefnon iohitw'il be equallysuppliedxto; he g i which maybe opened shall be desired to blow '01 lpehirficfiflmbers 16 are extended over the glnsfiiii a-nianner practicallycorresponding ,1, with thatfs'hown inLet'ters Patent No. 700, 347granted tomyself on the th day of May, 5' 1902, 'by. reference to whichit will be seen I-that said extensions, which arehere designated 3 120,are provided with discharge-spouts '2-1, 1; serving to direct thedischarge of air againstthe saws; 22 -to remove the hint from said- ,io, 'saws'i-f -Discharge-chutes 22 serve .to-convey the hilt fromthegins'to the condensers 23, as I shown in my Letters Patent .abovereferred to. "The discharge spouts or nozzles 21, as in "my LettersPatent above referred to, have dis- 2 charge mouths consistingofelongated slots,

I The operation and' .advantages of, this invension will bereadilj'understood-from the fore-l going description,taken inconnectionwith the go accompanying drawings, by those skilled in the art to whichit appertains.- Thefan is'ob-' viously to be made of .suflicientcapacity toaccomplish the several purposes of the inven ytion; but it.is equally obvious that. by usiuga 5 single fan in the manner hereindescribed much of the initial expense in settingup'the'plant maybesaved, the saving being not only in the substitution of *asingl e fanfor .a plurality of; .fans, but also largely inthe saving of power, 40machinery, belting, and the like, When the fan is started in operation,suction is established in thesuction-tube 5nd in the branches 6 and7;-of the latter, thusenabling cottongto be unloaded? fed, respectively,

" gin-stands. .The' air entering thesuctioigtubes with'the cotton willpass throughthesereens .11 and-'12 together with dirt and trash'separated from the cotton,--which will passthrough the suction-pipe!) andthrough the fan-casing intothe compressingschaniber under the indined-board or deflector 1,3, under which dirt and trash pass'alongfwi'th a blast of air which I carries-such dirt and trash throughthe seedduct along with the'seed .and'to the place of depositofthelatter. A largeiproportion of. the air coming from the fan-case isdiverted i-nto theupper ,p'ortion of the compressing chamber, the airthus diverted having been 60, freed from dirt and trash, as beforedescribed. It wilh'thus' bepure air that finds its way through the'ducts15 and the flaring mouths fI-ofsaid ducts into the air-chambers 16, fromhence-the air'passe's into, the gins where it to detach the'lint fromthe saws, as
